Specification forming part of Letters Patent No. 120,684, dated November'7, 1871.

To all whom it may concern:

Be it known that I, JEROME H. ToMLnvsoN, of Mount Carroll, in the countyof Carroll and State of Illinois, have invented a new and ImprovedCultivator; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawing forming part of this specilication.

Figure l represents a plan or top view, partly in section, of myimproved plow. Fig. 2 is a longitudinal vertical section of the same onthe line c c of Fig. l. Fig. 3 is a detail transverse section of thesame on the line K K, Fig. l.

Similarletters of reference indicate corresponding parts.

The object of this invention is to so connect the plow-beams with theaxle-bearings of the wheels that thelateral motion of the plows will beinversely followed by a similar twist of the wheels.

A in the drawing is the cross-bar of the frame, to which the pole orshaft B is rigidly secured. C C are the wheels, hung on pins or axles@that project from vertical posts B. These posts are swivel'ed inbearings d and e formed respectively on the under side of the cross-barand on horizontal plates f, which are bolted to and under pendent framesD attached to the cross-bar. The wheels, being thus hung to theswivel-posts, can be swung to the right or left at will. E E are theplow-beams. Their front ends are hung to vertical swivel-posts g, whichcan turn in the frames D. Cranks h of the posts g are, by diagonalbraces t' t', connected with a front yoke, F, whose ends are affixed toarms 7' projecting from the posts b. The posts b and g are thusconnected to each other so that when the plows are swung to the rightthe wheels will also turn to the right, and vice versa.

The operator has complete power to govern the side movement of theforward as well as the hind end of the plows, and crooked rows can beplowed with greater ease than without this de vice. The plow requiresless care in driving, for the wheels will adjust themselves to keepalways in front of the plows. No up or down movement oi the plows, onlytheir side movement, will affect the motion ofthe wheels. /Vhenever theteam gets oi' the rows it is only necessary to swing the plows aside,whereby the wheels are set so as to affect the motion of lthe wheel.

I am aware that a patent has been granted for placing the wheels of aplow or cultivator in such relation to a hand-lever that the wheels andplowframe can be kept in the direction ofthe row and run out to the endthereof after the horse has turned; and I do not desire to make claim toany such device; but

What I do esteem as my invention, and desire to protect by LettersPatent, is-

A wheel-cultivator having the end-pivoted beams E E of the plowsattached by the described connecting mechanism to the pivoted axles ofwheels C C, as described, so that as the plowman moves the handles ofhis plows laterally both plows and wheels will correspondingly adaptthemselves to the sinuosities of the rows and avoid cutting up theplants.
